Platen Printing-Presses, of which the following lis ai specification.

This invention relates' to devices commonly known as joggers for straightening up the pile of paper as' the sheets are delivered on the piling-table from a printing-press, and is designed to save the time and labor of doing the Work by hand.

The invention is particularly applicable to platenpresses, and consists in the novel construction, cornbination, and arrangement of parts hereinafter dey scribed and pointed out in the claims.

I accomplish the objects of my invention by the mechanism illustrated in the accompanying drawings,

in which- Figure 1 is a view in perspective of ymy invention detached from the printing-press. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3 is a detail in top plan view of the diagonallybent operating-bar. Fig. 4 is a detail in side elevation, and Fig. 5 a detail in under-side view of the operating-bar'working in conjunction with the bent bar.

Like characters of reference indicate like parts throughout the several views. v

In the drawings, 6 represents my improved jogging table which will be attached to the printing-press (not shown) in the usual manner, and is provided at its forward side with a straightening-strip 7. A portion of the upper side of the table 6 is counter-sunk, as

indicated at 8, for the reception of the mechanism for operating the jogging-plates 9 and 10. 11 is a post the reduced end of which is inserted in one of the holes 12, here shown as five in number arranged at varying distances from the middle of the table, whereby the post majr be changed in its position to suit the varying sizes of the printed sheets discharged from the press upon said table. The sheets of paper as they are delivered from the press after being printed, are deposited on the jogging-table 6 between Ithev straightening-strip 7, post 11,` and the jogging plates 9 and 10. The plates 9'and 10 are moved out to allow the sheet to be deposited without interference and are then moved inwardly against the printed sheets in two directions to crowd each sheet firmly against the straigh-tening-strip 7 and the post 11, the strip 7, post 11, and jogging plates 9 and 10, thus acting conjointly to move the printed sheets into an even pile-as the work progresses. p

The simultaneous outward and then inward-travel of the jogging-plates constitutes the essential feature of my invention and will now :be described.

15 is the main operating bar, which extends through the straightening-strip 7 and thence across the joggingtable 6. It passes through the counter-sunk portion 8 and lies within a groove 16 leading from the countersunk part 8. The operating bar 15 is bent to form the diagonal portion 20, and is bent again to form the part 2l, approximately at right angles to the bar 15, con'- necting said bar with the diagonal portion 20. The diagonal portion 20 is cut away approximately half of its diameter on its upper side, as shown in Fig. 3, to allow for the play thereon of the transverse operating bar 24.

The latter is provided with the underside dove-tailthe present invention'it is directed by means of the' groove 28 formed in the jogging-table 6.

The jogging-plate 9 is fastened to the transverse operating-bar 24 by means of the bolt 29 which passes through the plate and termniates at its lower end with a hook which grasps the bar 24 inthe manner clearly shown in Fig. 2. The upper threaded end of the bolt 29 has the wing-nut 30 by means of which the plate' 9 is bolted securely to the bar 24, and it also affords the means whereby the plate 9 may be adjusted longitudinally of the bar24 to meet the requirements of different sized sheets which are to be straightened. The jogging-plate 10 is attached to the main operating bar l5 by means of a similar hook-bolt 29 having a like wingnut 30 on its upper threaded end.

The main operating bar 15 is bent down in a U- shaped loop around the outer edge of the jogging-table 6 and is continued forward under the table as the bar 32, which terminates in the end hook 33, in front of the straightening strip 7, in the path of the platen of the printing-press. By the contact of the platen with the end 33 of bar 32, the latter will be forced back thereby.

carrying with it the integrally attached operating bar 15. The bar 32 will pass through the guides 35 on the under side of the table 6. It will have the hook 38 for the attachment thereto of an end of a coiled spring 39, and the other end of the spring 39 will be attached to the guides 35 or other fixed part of the jogging-table. The purpose of this spring is to return the operating bars to positions which will maintain the jogging-plate in contact with the printed sheets on the table. When the device is in use the operatingbars within the counter-sunk portion 8'will., preferably be protected by means of a metal plate or cover38 (see Fig. 2).

The operation of my invention will be readily understood from the drawings and above description. By the contact of the platen against the end 33 of rod 32 the integral upper bar 15 will be moved longitudinally thereby moving the -jogging-plate 10 away from the straightening strip 7, and the transverse bar 24 will vbe moved longitudinally at right angles, in a direction to carry the jogging-plate 9 away from the post l1. Ample room for the discharge of the printed sheet upon table 6 is thus secured, and upon the release of the rod 1. In a jogger, a table, `a main operating rodV extending transversely of the table; having an oblique portion formed by bending said rori` an auxiliary operating rod at right angles to the main rod having means engaging the oblique portion of the main rod to impart reclprocatory movement ln` both directions to the auxiliary rod by a longitudinal movement of the main rod. jogging plates carried by each of said rods, and means for'moving the main rod.
